BusWays
Non Segregated Phase Type

Park Bus Duct is custom designed, manufactured and tested as per the latest ANSI C.37.20 standards to meet customer specifications. It is a completely coordinated package of equipment with all the auxiliary material and supports for connecting transformers, switchgear, MCC1s and motors.

Features

Non-segregated phase bus
600V thru 38KV
Up to 12000A ratings
Aluminum, steel or stainless steel housing
Insulated with powder epoxy applied by fluidized bed process
Complete line of fittings provides for any configuration
Indoor trapeze and outdoor column support

Flanged Ends
     A flanged end is used to terminate the bus into switchgear, motor control centers, switchboards, or any rigid bus-to-bus connection. It consists of a gasketed equipment flange, up to 1'-0" of 3P-3W conductor (3P-4W as applicable), necessary insulation tapes, and required bolting hardware.

Cable Tap Box
      A cable tap box includes a gasketed and accessible termination box, lugs, necessary insulation tape (between bus and lugs only), and required bolting hardware. Lug sizes and quantity should be specified by purchaser.

Transformer / Generator Connection
      Will include the same components as a flanged end plus one set of flexible braid type connectors and a terminal box (if required).

Bushing Box (Weatherhead)
      A bushing box is used on service entrance run where the cable connection to the bus must be made via porcelain bushings. It is comprised of the same components as a transformer connection plus 3 through stud type apparatus bushings, bushing stud connectors (lug pads) and a strip heater.

Ground Bus
      The bus housing is designed and constructed to provide an electrically continuous ground path. The side rails of the bus housings are capable of carrying the full rated phase current continuously and, under short circuit conditions, are capable of carrying up to 60KA RMS asymmetrical fault current for 3-seconds. Consequently, a separate ground bus is not necessary unless specified.

Wall Entrance Seal
     A wall entrance seal consists of a wall throat, wall flange (one side of wall only), and a barrier which prevents air or vapor from passing from one room to another or from outdoors to

Equipment Entrance Seal
     An equipment entrance seal is needed when a barrier is required to prevent the passing of flame and/or gas between the bus housing and the terminating equipment.

Expansion Fittings
     An expansion fitting is used to counteract the strain placed on the bus due to the expansion and contraction of the building or the bus itself. Expansion fittings should be used whenever the bus run crosses a building expansion joint and whenever a straight run of bus exceeds 60 feet.

Flexible Housing (Misalignment) Collar
      This is required at terminations or wall penetrations when vibrations due to seismic forces may cause damage to the bus. It may also be used to adjust for the "settling" of terminating equipment after installation.

Supporting Steel (Hangers)
      Supports should be added on the basis of one for every 10 ft. for indoor and one for every 12 ft. for outdoor. Indoor supports are a trapeze type hanger while outdoor supports are e a single or double column type support.

Hazardous or Seismic Locations
      Consult Park for bus runs which are to be installed in a location which is classified as hazardous or in a Zone 3 or Zone 4 seismic location.

Housings

Aluminum, steel and stainless steel housings are available to meet a variety of environments Non-Magnetic housings are supplied at ratings above 2000 Amperes.
Outdoor housings are weatherproof and furnished with screened breathers and electric space heaters for condensation control.
Covers are gasketed sloped to shed rain and are removable top and bottom.
Ventilated indoor buses with louvers top and bottom covers are available.
500-watt, 240-volt heaters, operated at 120 volts and mounted via weatherproof junction box for easy removal, are supplied on 7' to 8' centers on outdoor bus systems. Facilities are supplied for connecting heaters to purchaser's power supply

Conductors
Buses are supplied with copper or aluminum conductors per purchaser's specifications. Tin or silver-plated contact surfaces at all joints or terminations. Internal or external ground bars or neutral bars are available as required.

Insulation
Bus bars are insulated with powder epoxy or porcelain, and mounted with corona control devices in molded Valox¹support blocks. Bars are firmly secured against movement during short circuit current to rated levels.
